ok… 1hr flight yesterday and it still appeared to be using more fuel than calculated.
via simbrief, with the new plane specs as previously discussed in the A32NX Dev ver 3c61594
today, Seattle to Denver. Wind info also entered into MCDU CLB CRZ DES profiles, all altitudes. Had the 60kn tailwind allowed for in the Simbrief FP.
BLOCK FUEL 6.5t
TOW less the estimated Landing Weight 65.6 - 61.6 = 4t fuel estimated
the actual fuel used was 4.9t
I cross checked the sim weights versus the simbrief/MCDU weights and all seemed to correlate. I flew very close to the planned profile, and even optimized the descent for fuel conservation. I was assigned a slightly longer approach, but not 30 minutes longer. The Cost Index was also correct in the FP and the MCDU. Finally I Departed 20 minutes behind schedule… and arrived 20 minutes behind schedule.
I am no expert… so very open to the idea of having missed something, but I can’t see it, and found my previous efforts to be accurate.
I reckon I am going to do another flight, and if I get similar results, allow for extra 23% fuel consumption or P23 Fuel Factor in simbrief
actual weight in pics… due to slide limitations, there was a 0.1t TOW rounding difference… ie no impact
at the gate after landing and sitting while.
